Rant on stencil

I really want access to some stencil buffer without having to gut the whole engine so...
Maybe SceneLayer could be a first class object, defining batching group and giving stencil access to the Scene to do easy masking/blending between whole object layers, all SceneObject in a SceneLayer should be really get batched together.

I really need to find some time to go play with his branch, making the Layer an object is definitively a move in the right direction. Not sure he has got all the batching right yet, but he seem to have changed so much about the renderer that i might be loosing my time gutting what's in torque currently. Looked a bit more carefully how the blending are currently routed down and the rabbit hole goes quite deep... i am contemplating to instead add a way to connect SceneBatchListener of some sort who could tell consumer when a new batch (or specific named layer/batch?) is submitted and hack my way into the batch/render query directly from there to manipulate their stencil as a quick hack. So not quite sure how yet, but i WILL get to them eventually ;)

He's implemented a new layer system based on SimSet. Something to perhaps look at:

I've spent a lot of time fooling around with blending, and yeah, T2D is pretty restricted in what it can do since it only uses glBlendFunc, instead of glBlendFuncSeparate.
